Hey there!
We need to find a common denominator.
5*3= 15
4/5= 12/15
2/3= 10/15
12+10=22
22/15
or
1 7/15
I hope this helps!

Sugar is needed for scientists to grow plants
As you stated before, cellulose is found throughout the cell walls of plant cells. Cellulose makes cell walls rigid, so that would indicate that cellulose is a carbohydrate.
Carbon is the best answer while other elements can be sodium, Lithium, or sulfur. It combines with hydrogen easily, and is the basis for all fossil fuels and organic materials.
